looking for light-weight data persistence solution in perl

Question

In my app I need to store some simple data both in memroy and in disk. A real database will be overkill in my case, so I need lighter one to handle the simple data persistence r

Answer 1

Do you want your data to be transparently persisted, i.e. you won't have to worry about doing a commit()-type operation after every write? I just asked a very similar question: Simple, modern, robust, transparent persistence of data strutures for Perl, and listed all the solutions I found.

If you do want transparent persistence (autocommit), then DBM::Deep may be easier to use than Storable. Here is example code that works out of the box:

use DBM::Deep;

tie my %db, 'DBM::Deep', 'file.db';

if ( exists $db{foo}->{bar} ) {
    print $db{foo}->{bar}, "\n"
} else {
    $db{foo}->{bar} = 'baz';
}
